ADJUSTABLE RECLINING-CHAIR.

SPECIFICATION forming part of Letters Patent No. 336,115, dated February16l 1886.

Application filed March 30, 1885.

T all whom it may concern:

Y Be it known that I, ARTHUR OGDEN HUB- BARD, a citizen of the UnitedStates, and a resident of Sauk Centre, county of Stearns, and State ofMinnesota, have invented certain new and useful Improvements inAdjustable Reclining-Chairs, of which the following specication is afull, clear, and exact description, reference being also had to theaccompanying drawings, in which- Figure l is a side elevation, Fig. 2 isa front elevation, and Fig. 3 is a rear elevation, of one of the chairscomplete. Fig. 4 is a detached perspective View of the foot-rest. Fig. 5is a detail in section of aportion of the armrest, 85e. Figs. 6 and 7are enlarged detached details of the brake mechanism. Figs. 8,v 9, andare details illustrating the construction of the seat portion of thechair. Figs. 1l and l2 are enlarged perspective views of the seatbraceclamping-joint.

A A'l are two bars forming the sides of the back-section, B B'l twosimilar bars forming the sides of the seat-section, and C C2 two similarbars forming the sides of the foot-section, the lower ends of thebackbars A A2 being united by hinges a to the rear endsof the seat-barsB B2, while the upper ends of the foot-bars C C2 are united by hinges c2to the forward ends of the seat-bars B B2. The hinges a are detachable,so that the back-bars may be disconnected from the seat-bars when A thechair is to be folded up, as hereinafter explained.

Any suitable form of hinge may be used; but in practice I have foundthat simple screweyes answer the purpose admirably. The back-bars A A2and the foot-bars C C2 are perforated, as shown, to receive lacing-cordsb, by which the canvas or other textile body or web D may be secured tothe bars, as shown. The outer edges of the bars A A2 and C C2 aregrooved, as shown at d in Fig. l, the grooves connecting the outer endsof perforations, so that the 1acingcords b will be elnbedded in thebars, and not only out of sight, except from the sides, but protectedfrom wear by the over-projecting wood of the bars. The lacing is held inthe grooves, as it reaches from one perforation to another, by beingdrawn taut in the perforations. At its ends the web D will be turnedover and sewed Serial No. 160, 598.

down, leaving heins, in which the end bars, A3 and C, will be inserted.These end bars are held in the ends of the bars A A2 and C C2 by tenonson their ends fitting into mortises in the ends ot' the bars, as shown.The lacings b, by being drawn tight, will thus hold the side bars inplace with reference to the web, while the hems on the web will hold theend bars in place iu the bars. The lacings also permit the web to beeasily and quickly tightened in event of its becoming loosened, or thereplacing of a worn or torn web., The webs may be of any suitablematerialcanvas, carpet, or other materialor a con1- bin-ation of two ormore materials. The Seatsection is re-enforced underneath by an extraweb, E, (see Fig. S, 9, and 10,) which is formed of a tube of canvashaving circular bars F F2 in its interior, by which it may be secured tothe inner edges of the seat-bars B B2 by screws or nails c. The web Dlies over this auxiliary web E loosely, and completely hides it, thefunction of the latter being to give additional support to the web D,where the greatest strains occur. On the inner lower edges, at thecenters of the bars B B2, metal sockets G G2 are secured, eachsupporting one end of a brace, H H2, each of the latter being providedon its other end with a clampingplate, K K2, the adjacent surfaces ofthe latter being provided with radiating intcrloclc ing notches 7i, (seeFigs. ll and 12,) and adapted to be clamped together by a bolt, fi. Itwill be readily understood, therefore, that' by loosening the bolt t'until the plates K K2 are disconnected, the bars H HAZ may be pushedupward by their lower ends, and spread the bars B B2 apart, and holdthem thus by again tightening up the bolt t'. By this means the bars BB2 are not only held apart and prevented from being drawn toward eachother by the pressure upon the webs D and E, but the latter may beretightened in event of sagging.

M M2 are the armrests, which are connected at their rear ends bybrackets to the back-bars A A2, near their lower ends, while the forwardends of the armrests are connected by similar brackets to the foot-barsC C2, as.,

shown. These brackets consistof small metal bars N', pivoted by theirends in the ends ot' the arm-rests, and also in slots cut into the ICOets N N2 are each of them rigid, so far as their connections with theback and foot sections are concerned, and have the armrests pivotedloosely in their outer ends. Attached to the under side ot' eacharm-rest is a chock7 or ro stop, P', whose functions are to check andregulate the throw of the chair, as hereinafter shown.

The three sections above described,vand covered with the web D, arearranged to be mount- 1 5 ed upon and supported by a folding base orframe, as shown. This frame consists of two legs, R' R2, pivoted at n tothe seat-bars B B2, near their forward ends, and having two othershorter legs, R3 R2 pivoted at r to the legs R 2o R2, the legs R R2being also connected together by a round, R2, and the legs R3 R4 beingsimilarly connected by around, R, while a chain or chains, R2, arearranged to connect the rounds, to prevent the legs spreading too farapart,

while at the same time adapted to allow the frame to be folded up, ashereinafter shown.

R8 R9 are two arms rigidly fixed by opposite bracing-bars, t t2, whichconnect their lower ends to the legs R R2, while their upper 5') endsare pivoted at n to the back-bars A A2,

near their lower ends, Aas shown. By this means the jointed back, seat,and foot sections are poised upon the. frame,and may be bent upward intoa chair shape with the back and foot sections at right angles to theseat-section; or the back-section may be turned down to nearly ahorizontal position, which, by reason of its having the arm-restspivoted thereto, will cause the foot-section to be thrown 4o upward to acorrespondingly-horizontal position, and thus transform the chair into acouch. Ot' course the chair may be placed in any intermediate positionwhich may be desired. The A"chocks or "stops7 P are so arranged that,when the chair is bent up into the form of an ordinary chair, the lowerends of the chocks will strike the seat-section and arrest the furtherforward movement, and preventthe back-section folding over upon theother 5o parts or upon the occupant of the chair. The

checks also perform the same office when the .chair is transformed intoacouch, by striking the seat-section at the other endof the stroke andpreventing the back section from sinking too low. Beneath each of thechocksPcurved guides P2 are attached to the seatsections,and providedwith channels in theirupper faces, in which the lower ends of the checksrun, to prevent the clothing of the occupants of the 6o chair fromcatching beneath the checks.

T is a rod passing through the arms R8 R2, and provided on one end witha head, c', and on the other with a cam hand-wheel, T2.

T3 is a bar pivoted by one end at o2 to the '65 side bar, B, and havinga slot, v4, in its other end, through which therod T passes.

T4 is a small cam-disk,having lugson its rear face by which it fits overthe vbar T2, and is prevented from turning thereon, and havingclutch-teeth c5 on its outer face corresponding to similar teeth, c", onthe cam hand-wheel T2. The rod T passes through the slot in the bar T2,and also through the cam-disk T2, and is rigidly fixed in the hand-wheelT2. By this simple device a brake is formed by which the bar T3 may beclamped to the arms R8 R9. and thus hold the chair at whateverinclination the occupant may desire. The length of the rod T will begraduated to correspond with the distance between the arms RB R9, sothat when the straight sides of the teeth v2 o6 are in contact the barT3 will be loose and free to be moved by the adjustment of the chair;but when it is desired to lock the chair in any desired position,tl1enit is only necessary for the occupant to turn the hand-wheel T2, whichwill cause the clutch-teeth to move the handwheel away from the cam-diskand compress the bar T3 firmly between the arm R8 and the cam-disk. Afoot-rest is arranged upon the chair, consisting of a main bar orfoot-rest, fw',

and two small side bars, 102 w, the latter pro.- vided with small pegsww5,which are adapted to rest above and below the foot-bars C C2 when'the rest is inserted into its place, as shown in Figs. l and 2. The pegsw* thus hold the rear end ofthe footrest and preventits being pushed outby the foot of the operator. Additional pegs, will be inserted into thelower sides of the bars C C2, above which the pegs w* may be placed whenit is desired to adjust the rest to suit younger or shorter occupants ofthe chair.

The connections between the supportingframe and the chair or seatport-ion will he so arranged that they may be disconnected to enabletlie chair to befolded up for transportation. Nearly all' the otherparts are also adapted to be disconnected, so that the-chair may befolded up into a small space for convenience of transportation.

Having described my invention and set forth its merits, what I claimisl. The seat-section, back-section, and footsection hinged together andhaving the web D, attached thereto by lacings b, and provided withbrackets N N2 and arm-rests M M2, connecting said brackets, incombination with a folding supporting-frame consisting of legs R R2,pivoted to said seat-section, bracing-legs Ra R4, exible connections R2,and arms R8 R, attached by one end to said legs R R2, and pivoted tosaid back-section by their other ends, substantially as and for thepurpose set forth.
